Problem description

The key bindings docs over at https://www.sublimetext.com/docs/key_bindings.html don't yet cover the new context keys introduced in 4xxx builds.

Preferred solution

Add the new context keys to the docs. Here's a summary of them

Key	Operand	Operators	Match All	Description	Added in
"overlay_has_focus"	boolean	equality	no	Whether the overlay currently open, has focus.	4082
"overlay_name"	string	equality	no	The name of the overlay. Valid values are "goto" & "command_palette"	4082
"group_has_multiselect"	boolean	equality	no	Whether the currently focused group has multi selected tabs.	4050
"group_has_transient_sheet"	boolean	equality	no	Whether the currently focused group has a transient sheet.	4050
"has_snippet"	boolean	equality	no	Whether the immediate word before the cursor can be expanded to a snippet.	4050
"is_javadoc"	boolean	equality	yes		4050

Alternatives

None

is_javadoc is supported by core??? Interesting.

@deathaxe Yes

I don't think multiline block comments are related to javadoc by nature. Even Java distinghuishes them.

No JavaDoc

/*
 *
 */

JavaDoc

/**
 *
 */

In both one might want to add the leading * on each line, Or it being deleted once the line is joined with the previous one :-)

Without double checking it, I'd say the preceding_text pattern together with selector should be enough.

The only reference I have to what the is_javadoc context key probably does is this https://discord.com/channels/280102180189634562/280157083356233728/780449702482542612
